WIND-ACTUATED vENT1LAToR.

. Specification of Letters Patent.

Application filed March 23, 1908. Serial N o. 422,825.

To alt whom it may concern:

Be it known that I, .IosErE FIsoI-IER, a citif zen of the United States, residing at Indianf apolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Vind-Actuated Ventilators, of which-the following is a specification.

This invention relates to ventilators having closed tops and provided with sidedischarge openings applicable for chimneys or places where it is desired to carry out smoke, nauseous and gaseous air; and the object of the invention is to provide ventilators which are operated by the action of the wind so that the discharge ends of the ventilators will stand at all times in the direction in which the wind is blowing.

A further object consists in providing ventilators with hoods which are supported by means located externally of the chutes so as to leave the latter unobstructed for free passage of the smoke.

I accomplish the objects of my invention by the ventilator illustrated in the accompanying drawings, forming a part hereof, in which- Figure 1 is a front elevation of the ventilator. Fig. 2 is a side elevation of the construction shown in Fig. 1, except that the hood is shown in section. Fig. 3 is a cross section on the line 3 3 in Fig. 2. Fig. A is a fragmentary detail sectional view, on an enlarged scale, through the bearing for mounting the rotating hood. Fig. 5 is-a side elevation of the ventilator composed of cement or similar material.

In the drawings, 1 represents the duct or chute, usually composed of galvanized iron or similar material, leading from the top of the chimney or opening in the roof through which the smoke or air is discharged. The chute is formed so as to correspond to the style of chimney to which it is to be attached, or the'opening to be covered. 2 is the hood which is somewhat larger in diameter and takes over the upper end of the chute 1, as

shown. The hood 2 is provided with a conically shaped roof 3 to direct the water over the sides' of the hood. The hood 2 is, also, provided with the discharge l opening 5 through which the smoke, air and gas is permitted to escape. The discharge opening 5 is usually formed by making a longitudinal slit in the side wall of the hood and then bending the adjacent material outward to form the wings 7. These wings catch the wmdand thus move the hood so as to keep the discharge opening 5 set in the direction inwhich the wind is blowing. The hood is` supported and held in operating position by means of the bar 10 which is attached to one side of the chute 1 and then passes upward and over the hood and thence downward and attaches to the opposite side of the chute, as shown in Fig. 1 of the drawings. The hood is mounted so as to ride on a roller bearing to reduce the friction and thereby insure that the hood will be operated and susceptible to the slightest current of air. The bearing for accomplishing this result is best shown in Fig. t of the drawings, and consists of a glass cup 12 which forms the lower portion of the bearing. The cup 12 has an integrally formed boss 13 which engages an aperture in the supporting-rod 10, whereby the cup is firmly held in position. A second cup 15, having a greater diameter than the' cup 12, overlies the latter cup so that foreign matter will be excluded from entering between the cups 12 and-15, to impede the movement of the balls 16. A shaft 17 passes vertically through the cups 12 and 15 and is ,provided with the shoulder 18 adapted to rest upon the upper bearing-cup 15, to limit the insertion of the rod or shaft 17 The shaft 17 below the lower end of the boss 13 is reduced in size to provide the shoulder 20 against whichthe top 3 of the hood rests. The lower end of the shaft 17, which projects into the interior of the hood, is provided with threads to receive the locknut 22 by which means the hood is securely held to the shaft.

In addition to the wings 7V I may, if desired, provide the vane 25, which is attached to the shaft 17 so that the possibility of the hood not responding to the slightest breeze is prevented. The vane 25, in addition to insuring the operation of the liood, makes the ventilator, as a whole, more attractive and ornamental. The ornamentation may be further extended by placing a suitable embellishment on the upper end of the shaft 17.

Fig. 5 illustrates one of the many pleasing eects that may be attained in ventilators to adorn chimneys which are composed of cement and like material, -and which comes within the scope of this invention. The ventilators composed of cement and the like operate in the same manner as if constructed of iron or other metal.

Patented Oct. 13, 1908.

Having thus fully described my said invention, what I desireto secure by Letters Patent, is-

A Wind actuated ventilator including the duct, a revoluble hood adapted to take over the upperend of said duct and provided With a laterally disposed discharge opening, a hood supporting means secured to the exterior surface of said duct and provided with an aperture, a bearing-cup provided With a boss to engage the aperture inV the hood supporting means, an upper bearing -cup adapted to overlie the lower bearingcup, balls between the said cups, a shaft passing vertically through the cups and into the hood, means ou the shaft to limit its i11- sertion, and a locking` means adapted to secure the hood to the vertical shaft.

lu Witness whereof, I, have hereunto set my hand and seal at Indianapolis, Indiana, 20

`this 18th day of March, A. D. one thousand Vnine hundred and eight.
